Claims.

This invention relates to apparatus for treatmg textile material and more particularly to mechanism for stopping the travel of an andless string of material being treated. to make the material available for inspection at a predetermined location in the string.

T'e'xtile materials "are commonl dyed, bleached or otherwise treated in a machine which is'provided with rolls for advancing an endless string of material through a treating liquid. The endless string of material may constitute a single piecewith itsends sewed together, or it may be constituted of a plurality of pieces "sewed together endQco-end. The string is sometimes quite long, frequently exceeding 1600 yards. It is necessary that every portion of the string be uniformly dyed or otherwise treated, and in order to'accomplish this it is necessary "to inspect the fabric repeatedly. Each inspection should be made at the same location sw n the string so that leveln'ess of treatment of all ofthe material in the string may be assured. For accomplish ing this it has been customary 'for an operator towatch the stringent stop its travel at a .predetermined point, such as at a selected seam, each timeatest is to be made. When there are a number b'fseams, sometimes twenty, more or 1e's's, a seam desiredto be located 'maycome into and pass 'from View Withbli't det ction, and. the o erate may be exlfibsed "t6 'lisi'ing vapors for quite a long time before he detects the seam desired and sto s themachi'ne. 7 It is among the objects of the invention to provide for stopping the travel of an endless string of material b'ingtre'ated so as to make aces'sible'for inspection a'g'i'ven'area ofthe mat'rial as "it travels through a tank containing iiiiid-treating liquid. The apparatus for accomplishing this result is so constructed and arranged as to be effective for stopping thetravel (if the' endless string Within a relatively short t me after the 'st'ofipi g 'rnecha'ni'sm has been set, regardless of-the length of the strin g and the ocation inthe apparatus of the. ortion er string containing the area to be inspected.

, {mother objct'oi'the invention is to rov-me mechanism settable at will for automatically interrupting the travel of" an" endless string.

Further and other objects ofthe present invention will be hereinafter set forth in the accompanying specification and clairn'sand demonstrated by the drawings whichsho-w by way of illustration a pref ed" v I bodiment and the iii'incible of the ii'iventi'dn'a'iid'ifihat "is now considered the best mode-of applying that iiiinciiile.

The structure of the present invention is shown as embodied in a dyeing machine having a tank ill through which an endless string of textile material I] is advanced. The string is helically draped over a pair of driven rolls i2 and it, in such a manner that the various convolutions of the string, as shown in Fig. ,1, pass upwardly to and over roll I2, over roll i3 and down into the tank 10. The rolls are motordriven through a pulley 14 mounted on the shaft r' of roll I.2,and roll -l3 is driven from roll 12 by a belt connection 15. The string of textile material is usually disposed over these rolls in such amanner that it-descendsto the bottom of the tank and its slack rests in gatherings, such as illustrated at IS. The material is drawn upwardly from thegatherings, as shown at it, and passes over roll l2 and thenroll is in the next succeeding convolution and again descends to and is gathered in the tank, as shown at 18. The string of material travels inconvolutionsin like manner for the full length of the rolls or for any length of therolls required to be used. In the last convolution the. descending portion 9 of the string likewise passes through the liquid contained in the tank and: is then drawn upwardly, as shown ati-Zi, and over rolls i2 and is. The string is then returned, asfshown at 25-, to'enter the first-convolution at'the other end of the rolls. The machine is provided with a slidable Window 22 through which the travel of the string of material maybe observed. The window is displaceable so that. an operator may reach in and rearrange any entanglements which occur in the string. The machine is provided with a rockable rakebeam 23 which is pivotally mounted at its ends at and 25in journals carried by the frame of the machine. This rakebeam is in the form of a frame including a rock shaft 26 and tines or sticks 21, 2B, 29,,30, etc, equally spaced from each other and normally extending substantially horizontally over an opening to the tank. These sticks separate the rising portions of the several convolutions of the string of textile material being treated.

The rakebeam has mounted thereon a mercury switch 3i which closes a circuit when the rakebeam is in normal operating position as when the sticks 21, 28, 29, 3!], etc. are in a substantially horizontal position as shown in Fig. 2. This switch controls the circuit of the operating motor by which the rolls l2 and Bare driven and the string of material is advanced through the machine. An entanglement or bunching occurring in the string is carried upwardly in one or another of the rising portions of a convolution of the string and engages adjacent sticks of the rakebeam and rocks the rakebeam. This movement of the rakebeam opens the circuit to the operating motor and causes discontinuance of the travel of the string. The operators attention is drawn to the stoppage of the machine and he may then untangle the obstructing material and set the machine in operation for continuing the treatment.

In accomplishing the objects of the invention means are provided for reducing the areas for the passage of the string between pairs of sticks. As shown in Figs. 1 to 4, inclusive, this means comprises a bar 32 pivotally connected to the rakebeam 23 by means of a pair of links 33 and 34. The length of these links 33 and 34 is such that when the bar 32 is rocked upwardly towards the undersides of the sticks of the rakebeam the available space for the passage of the rising portions of each of the convolutions of the string is restricted. A bar 35 is preferably welded to the sticks forward of the rock shaft 26, as shown in Fig. 4. This bar defines the rearward limit of the available areas for the travel of the string.

As best seen in Fig. 4, a cable 36 is fastened to one end of the pivoted bar 32 and is threaded over pulleys 37 and 38. The free end of this cable has attached to it a weight 39 which is normally disposed on a shelf d0. Whenever it is desired to raise bar 32 to a position for reducing the available areas for the passage of the string between the, sticks of the rakebeam, the weight as is removed from the shelf and permitted to hang from the cable 36. The tensioned cable raises bar 32 from the position shown in Figs. 2 and 4 to the position shown in Fig. 3. If desired, a second cable 4i may be attached to the other end of the pivoted bar 32 and provided with a weight 42 for use in raising bar 32 and holding it in a raised position. Either or both of weights 39 and 42 may be utilized for accomplishing the same purpose.

A bob 43, which may constitute a rigid object of revolution simulating a pear, is attached to a string at any location where repeated inspections of the string are desired to be made. The bob may be of rubber or of any other suitable material and is of such size as normally to pass through the spaces between pairs of sticks of the rakebeam and to be prevented from passing therethrough when the available areas for the passage of the string are reduced as by the positioning of bar 32 in an elevated position, as

shown in Fig. 3. The bob is usually attached to a seam in the string by means of a band or cord at and it travels in a helical path along with the material being treated as the string is ad vanced through the machine.

Whenever an inspection of the progress of the dyeing or other treatment being effected is desired, the operator has only to remove weights 39 and 42 to apply tension to cables 36 and 5! and cause the raising of bar 32 into contact with the sticks 28, 29, 38, etc. of the rakebeam. In due course of time the bob will be carried by the string into contact with the bar 32 and between one or another pair of sticks and cause the rakebeam to be tilted sufiiciently to shut off the operating motor and stop the travel of the string. When this occurs the operator may remove a sample test piece from the fabric and then restore the weights 39 and 42 to their shelves so that the obstructing bar 32 will return to inoperative position under the pull of gravity. The

. machine may then be set in operation. This procedure may be repeated at irregular intervals and as often as is necessary to secure samples of the material being treated.

A different arrangement for positioning the obstructing bar for reducing the areas betweenthe sticks of the rakebeam is illustrated in Fig' 5. In this figure the bar 45 is similarly pivotally' attached to the two sticks 46 and ll at the endsv of the rakebeam. Bar 45 is normally held in an.

inoperative or depending position by means of a cable 58 to which a weight t!) is attached. When weight 49 is raised and supported on a shelf (not.

shown) bar 35 is drawn upwardly into operative position adjacent the sticks by means of a pair of springs 50 and 5|, which have their ends attached to the pivoted bar 35 and to the fixed bar 52 on the rakebeam.

Still another arrangement of structure by which the areas for the passage of the string through the rakebeam may be reduced is illus-. trated in Fig. 6. In this modification the rakebeam consists of two frames which are displaceable relative to each other to reduce the available spaces between sticks extending from the respective frames. One frame includes a rock shaft 53 pivotally mounted on the machine. Sticks 55, 55, 56, etc. are fixedly mounted on the shaft and extend over the opening of the tank.

A second frame includes a bar 51 which is carried on the shaft '53 and slidably supported by guides 53 which are fastened to the shaft. Bar 5'! is provided with sticks 59, 6d, 65, etc. which are disposed in alternating arrangement with sticks 54, 55, 56, etc. of the first frame. The spaces provided between pairs of successive bars of the assemblage normally correspond with the usual spaces provided in a rakebeam for the pas: sage of a string of material.

Alternate spaces may be reduced in area by sliding the bar 51 axially with respect to shaft 53. To accomplish this, a fork 62 is provided with its slot 63 adapted to engage opposite sides of one of the sticks 59 of the slidable bar. The fork 62 is loosely mounted on the rotatable shaft 64 so as to respond to the axial movement there of. The shaft 64 is threaded for engagement with the fixed nut 65. I A hand wheel 66 is provided to enable the operator to rotate the shaft es and thereby translate the slidable frame with respect to the pivoted frame whenever it is desired to reduce the areas between alternate pairs of sticks of the respective frames. Y

In each case the controlling mechanism for setting the means by which the areas between the sticks of the rakebeam is so arranged that the operator may accomplish a setting from the outside of the machine and without opening the machine. This invention is capable of numerous forms to the particular showing herein to indicate the scope of this invention.
